## Abstract **Let′s resolve our differences**: Implementation of an enantioselective Michael addition followed by an intramolecular aldol reaction catalyzed by two phosphoric acids has enabled the synthesis of cyclohexenone derivatives with excellent enantioselectivities. Prominent kinetic resoluti
## Abstract A novel cyclic dialkyl phosphate was synthesized starting from (+)‐diethyl tartrate. Its catalytic activity as a chiral Brønsted acid has been examined in the Mannich‐type reaction of a ketene silyl acetal with aldimines as a model reaction. The corresponding β‐amino acid esters were ob
